Struct slog_atomic::AtomicSwitch

pub struct AtomicSwitch<O = (), E = Never>(_);

Drain wrapping another drain, allowing atomic substitution in runtime

Methods

impl<O, E> AtomicSwitch<O, E>

fn new<D: SendSyncRefUnwindSafeDrain<Ok = O, Err = E> + 'static>(
    drain: D
) -> Self

Wrap drain in AtomicSwitch to allow swapping it later

Use AtomicSwitch::ctrl() to get a handle to it

fn new_from_arc(
    d: Arc<ArcCell<Box<SendSyncRefUnwindSafeDrain<Ok = O, Err = E>>>>
) -> Self

Create new AtomicSwitch from an existing Arc<...>

See AtomicSwitch::new()

fn ctrl(&self) -> AtomicSwitchCtrl<O, E>

Get a AtomicSwitchCtrl handle to control this AtomicSwitch drain

fn fuse(self) -> Fuse<Self> where
    Self::Err: Debug, 

Make Self panic when returning any errors
